Benchmark-based evaluation of portfolio performance: a characterization

Benchmarking is a universal practice in portfolio management and is well-studied in the optimal portfolio selection literature. This paper derives axiomatic foundations of the relative return, which underlies a benchmark-based evaluation of portfolio performance. We show that the existence of a benchmark naturally arises from a few basic axioms and is tightly linked to the economic theory. Our method relies on the use of both axiomatic and economic approaches to index number theory. We also analyze the problem of optimal portfolio selection under complete uncertainty about a future price system, where the objective function is the relative return.     

Trade Size Preference of Informed Traders in Indian Equity Markets

This study utilized high frequency transactions data to analyze the trade size preference of informed traders in Indian equity markets. It is observed that informed traders at an aggregate level adopt stealth trading strategy, wherein they prefer medium sized trades over large sized trades in order to camouflage their private information. However, the stealth trading behavior varies across stocks, wherein informed traders prefer more large sized trades on firms that are part of an index compared to non-index firms. Trading behavior also varies across other market conditions. It has been noted that informed traders prefer large sized trades during periods of high market thickness, negative returns, and low volatility. This study also provides a rationale for such varied behavior of informed traders.     

Is Supply's Actual Contribution to Sustainable Development Strategic and Operational?

This paper addresses the issue of how sustainable supply practices are actually used as a leverage for sustainable development (SD). In order to assess the level of sustainable supply management within an organization, the authors have reviewed the literature extensively and then developed a five‐step maturity model around five management dimensions. A qualitative exploratory approach based on two detailed case studies of organizations whose reputation for SD is recognized internationally has been used. This methodology allowed us to show (1) how sustainable supply practices could be used as a leverage for an organization's sustainable development approach and (2) that sustainable supply practices still have quite a distance to go with regards to the maturity model for sustainable supply, even in organizations that are often mentioned as leaders in the SD area. In these organizations, managers still emphasize environmental considerations, while neglecting practices that would make it possible to reach the three SD objectives simultaneously.

Is Current Way of Promoting Sustainability,Sustainable?

Consumer behavior regarding sustainable products has been a complex concept. There is a discrepancy between consumer’s espoused concern towards environment and their purchase of environment friendly products. Past literature suggests greenwashing being a possible reason for this discrepancy. With greenwashing being caused by mismatch between communication and perceived performance, this article focuses on assessment of simultaneous impact of both communication and performance elements on brand attitude. A quantitative study was undertaken to test the hypotheses. This was followed by a qualitative study to understand alternative explanation of hypotheses that was not accepted. The research revealed that a consumer’s attitude toward a green brand is impacted both by his or her general skepticism towards green ads and the credibility that she assigns to the firm’s green message. Perceived value of product also had a positive impact on brand attitude. Findings advance academic literature and support managerial community by highlighting factors for building a positive green brand attitude and resultantly avoiding the trap of being equated with greenwashing.     

On Measurement of Economic Growth

This article continues the discussion raised in the pages of the journal on the methodological problems of justifying economic policy [1]. Problems of measuring the inflationary component of economic growth and in product competitiveness in the internal market and external markets are considered. A procedure to measure economic growth, taking into account the balance of interests of the current and future generations, is proposed.

Poverty in US Lesbian and Gay Couple Households

Poverty is a widely researched topic in economics. However, despite growing research on the economic lives of lesbians and gay men in the United States since the mid 1990s, very little is known about poverty in same-sex couple households. This study uses American Community Survey data from 2010 to 2014 to calculate poverty rates for households headed by different-sex versus same-sex couples. Comparing households with similar characteristics, the results show that those headed by same-sex couples are more likely to be in poverty than those headed by different-sex married couples. Despite that overall disadvantage, a decomposition of the poverty risk shows that same-sex couples are protected from poverty by their higher levels of education and labor force participation, and their lower probability of having a child in the home. Lastly, the role of gender – above and beyond sexual orientation – is clear in the greater vulnerability to poverty for lesbian couples.     

Reliable Inference in Categorical Regression Analysis for Non‐randomly Coarsened Observations

In most surveys, one is confronted with missing or, more generally, coarse data. Traditional methods dealing with these data require strong, untestable and often doubtful assumptions, for example, coarsening at random. But due to the resulting, potentially severe bias, there is a growing interest in approaches that only include tenable knowledge about the coarsening process, leading to imprecise but reliable results. In this spirit, we study regression analysis with a coarse categorical‐dependent variable and precisely observed categorical covariates. Our (profile) likelihood‐based approach can incorporate weak knowledge about the coarsening process and thus offers a synthesis of traditional methods and cautious strategies refraining from any coarsening assumptions. This also allows a discussion of the uncertainty about the coarsening process, besides sampling uncertainty and model uncertainty. Our procedure is illustrated with data of the panel study ‘Labour market and social security' conducted by the Institute for Employment Research, whose questionnaire design produces coarse data.
